Restoring Win7, NIC IP Address

I'm using Acronis 2014 V3 build 6688. I have a number of identical i7 computers. When I create a master image of one of them(Win7), when I restore this image on the others, I end up with 4 NIC cards in the registry instead of only 2. And the IP address is reset to DHCP rather than the static IPs in the original PC. The PCs are not networked together.
This never happened previously when I used XP.
As it, Acronis does not restore the identical configuration as the original.
How can I fix or get around this without manually massaging the restored PCs?

Thanks
Ken
